Note: Notes and lyrics in LilyPond input must always be
surrounded by { curly braces }. The braces
should also be surrounded by a space unless they are at the
beginning or end of a line to avoid ambiguities. They may
be omitted in some examples in this manual, but don’t forget them
in your own music! For more information about the display of
examples in the manual, see How to read the manuals.
